*Title: The ability to output debug info based on current_user object_id.

*Documentation:
The ability to output debug info based on current_user object_id.

New INI setting in site.ini has been added:

-[DebugSettings].DebugByUser=enabled/disabled
 Whether debug is set per UserID. If set to enabled only users with
 IDs (in DebugUserIDList) can get debug.
-[DebugSettings].DebugUserIDList[]
  An array with UserIDs which will get debug information

for example:

[DebugSettings]
DebugByUser=enabled
DebugUserIDList[]=14
